Tasmania is showing off its small but savvy cropping industry to some of the nation's grains leaders this week.

The Grains Research & Development Corporation Board visited for a strategy meeting and chairman, Keith Perrett says there are particular challenges in the Tasmanian farming system.

"It's quite interesting this is a very complex farming system you have down here," he said.

"When you look at poppies are king and a profitable crop, they're going to be around for a while.

"They create some issues as far as the rest of the farming system.

"We're looking today at Michael Chilvers farm and a carrot [seed] crop and once again, trying to manage that and your options for herbicides become a little bit limited at times.

"One of the things we are seeing across the world but also Australia is herbicide resistance, something we have to manage."

Keith Perrett said Tasmania's current moratorium banning the production of genetically modified crops is another limit to the options for Tasmanian farmers.

"I think the world is going in that direction as a whole.

"The technology is not scary, it's not weird science.

"It's very much your basic plant breeding, just advanced, it's more precise.

"There is a problem with consumer perception though and that's got to be acknowledged.

"When you get into your major food crops such as wheat, it's quite obvious that the consumer is nt ready for that yet.

"So we have to be mindful of that."

"At some stage though, when there are products out there that consumers see a real benefit in (and that may be a benefit to the environment or a benefit through greater health) then I think you will see a greater acceptance.

"But that, that's time."

The Tasmanian Government is reviewing its moratorium against genetically modified food that expires in November 2014, and is inviting public submissions now.
